Concave Chest

I'm wondering if anyone has any tips for a novice. I have a pretty significant concave chest (born that way) and was wondering whether there is any way to build up my chest so that it looks a little more normal (see the photo in my profile).

I started doing inclined bench press. It seems harder especially if you push up from your chest and don't let gravity pull the bar back some. I had to drop my weight a little just to do a few sets of 10 when I normally do 100-110 5 sets of 10 regular bench press. Don't need to work shoulders already do that, shoulder press and military press behind my head.

Lol, I was looking for the topic where someone talked about there chest and just revived an old thread. I meant the thread about building the middle of your chest. I searched for that and there was several on that topic as well.
